Five shot dead inside home in Milwaukee

Five people, believed to be of the same family, were shot dead by a lone gunman in a home in the U.S. city of Milwaukee on late Monday morning.

The victims, aged from 14 to 41, were found dead inside a home after a man called 911 and said "his family was dead," local media reported citing police.

A baby inside the home survived, according to the Milwaukee Journal Sentinel.

The police recovered a weapon at the scene, and a 43-year-old suspected gunman has been arrested.

The suspect has several prior arrests in 2002, which "prohibit him from legally owning a gun," and the suspect and the victims were all known to each other, the media reported.

Police are investigating the case as an act of family violence.
